Forde says, "I'm telling everyone right now all across the world that's seen the video, the rat is not mine!"

INSIDE EDITION's Diane McInerney went back with him to the number 4 subway line in Manhattan, the exact spot where he shot his now famous video.

"Some people are actually saying well that rat looked too clean and too well fed," says Diane.

Forde replies, "The rats are well fed, there's a lot of garbage for them to eat here!"

Forde says he heard a woman scream on the train and that's when he got his camera out. He shows Diane where the rat ran under the seats and down the isle of the subway train. He says there was almost no one on the train because it was around 2 o'clock in the morning.
